The Polk County Sheriff's office said the plane went down about 12:30 p.m. Thursday in Tiger Creek Preserve south of Lake Wales.

A news release said 45-year-old Ronald Bramlage was piloting the plane headed from the Bahamas to Junction City, Kan. It had stopped for customs in Fort Pierce, Fla., and had taken off a half-hour before the crash.

On Friday morning, officials said they are still looking for the body of one of the young victims.

The sheriff's office said the single-turboprop, fixed wing plane started to break apart and crashed. When deputies reached the area by helicopter, it was clear no one had survived.

Bramlage was the owner of Roadside Ventures LLC in Junction City.

Plane has connection to Casey Anthony

The single-turboprop plane that crashed in Lake Wales has a connection to Casey Anthony.

Anthony flew on the plane when she left central Florida last summer after she was acquitted on murder charges.

Officials said the lawyer who owned the plane had sold it.

Anthony was on trial for the death of her daughter, Caylee Marie Anthony.
